WebThe Cullen–Harrison Act, named for its sponsors, Senator Pat Harrison and Representative Thomas H. Cullen, enacted by the United States Congress on March 21, 1933, and signed by President Franklin D. Roosevelt the following day, legalized the sale in the United States of beer with an alcohol content of 3.2% (by weight) and wine of similarly low alcohol content, … WebThe reason why we prefer to express the law with this equation is because absorbance is directly proportional to the other parameters, as long as the law is obeyed. We are not going to deal with deviations from the law. A = bc tells us that absorbance depends on the total quantity of the absorbing compound in the light path through the cuvette.
